I can probably get it back to original operating condition. Recalibrating the speedo requires a machine that I don't have and recalibrating the odo requires parts that I don't have. Most any speedo shop can do the speedo calibration, but the parts for the odo may be impossible to come by. I don't know if anyone has them any more. FWIW, the stock calibration may not be too far off. As a rule of thumb, a change in diameter of 10% (ie from 80 to 70) is pretty well compensated by an increase in width of 20 (ie 165 to 185.) So a 185SR15/70 would have just about the same rolling radius as a 165SR15(/80). - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- Search old messages on the Web!
